Die prozebsteuerung und datenerfassung der SOUSY-VHF-Radaranlage

Abstract

Central unit of the radar control and data acquisition is a 21M08 hewlett packard minicomputer with a real-time-II and file-manager execute system. Together with standard periphery and analog-digital converter, a radar controller controls the preprocessor, and the antenna control are connected to the computer. The radar controller controls the synchronous radar cycle and can generate phase-coded signals. The processor reduces the data rate of 4 MW/s from the AD-converter by a factor of thousand by averaging the signals. In addition the preprocessor can decode phase-coded signals. He averaging has the effect of a combfilter.
